steve, allow me to picture the Uros and their floating veggi platforms a bit.
In the sense of what we have discussed here so far those are segmented floating islands made of moduls (each totora piece a module) similar in tradition to richi sowas spiral island, compareable to “honeycomb structures” like nkossa, glomar beaufort, Kon Tiki and other “flat float solutions” or “raft solutions”.
Their islands are “non structural” means they are not a single piece of rigid and calculated engineering – they are hold together by friction and buoyacy forces. The load distribution on the islands is elastic. They take long waves by flexing somewhat. The connection beween islands is a “sparse connection”, the islands are designed for easy repair, and limited damage by storms.
And – and this is the most important thing – they have more squaremeters of island floating out there than we can dream of – without counting on big funding political and legal support.
